在信息信号处理过程中,如对信号的过滤、检测、预测等,都要使用滤波器,数字滤波器是数字信号处理(DSP,DigitalSignalProcessing)中使用最广泛的一种器件。常用的滤波器有无限长单位脉冲响应(ⅡR)滤波器和有限长单位脉冲响应(FIR)滤波器两种[1],其中,FIR滤波器能提供理想的线性相位响应,在整个频带上获得常数群时延从而得到零失真输出信号,同时它可以采用十分简单的算法实现,这两个优点使FIR滤波器成为明智的设计工程师的首选,在采用VHDL或VerilogHDL等硬件描述语言设计数字滤波器时,由于程序的编写往往不能达到良好优化而使滤波器性能表现一般。而采用调试好的IPCore需要向Altera公司购买。笔者采用了一种基于DSPBuilder的FPGA设计方法,使FIR滤波器设计较为简单易行,并能满足设计要求。

This paper addresses the issues relating to the enforcement of robust stability when implementing the Adaptive Inverse Control (AIC) scheme. In this scheme, an adaptive FIR filter is added to a closed-loop system in order to reduce the output error caused by external disturbances, enhancing the performance achieved by linear time-invariant controllers alone.
